Abstract
Eight new anthocyanins 1-8 (ternatins C1, C2, C3, C4, C5, and D3 and preternatins A3 and C4) were isolated from Clitoria ternatea flowers. By the application of chemical, UV-vis, and FABMS methods, the structures of 1-6 were postulated as delphinidin 3-malonylglucoside having 3'-GCGC-5'-G, 3'- GCGCG-5'-G, 3'-GC-5'-G, 3'-GCG-5'-G, 3'-G-5'-G, and 3'-GC-5'-GC, and compounds 7 and 8 as delphinidin 3-glucoside having 3'-GCG-5'-GCG and 3'- GCG-5'-G as side chains, respectively, in which Dp is delphinidin, G is D- glucose, and C is p-coumaric acid. The structures of the compounds 1, 3-5, and 7 were established completely by additional NMR methods.
